2 forum posts	I have recently aquired a fractional hp single phase motor for my lathe and need to reverse the direction of rotation. What is the correct way? I dont want to cross belts.

With the meter on the ohms range you will get a reading between the 2 wires comming from each winding . You need to reverse the connections to one winding only.
